doesn't matter who pays for something. it matters if the information provided is or isn't accurate and complete. The difference between a Govt paid item and a corporation paid item? the Govt item is usually provided by those in authority trying to persuade you of this or that and generally, has less opposition (since Govt positions generally provide promotion and contracts only for those who agree with the Govt in question) Corporations equally try to persuade people of what they want them to believe -- but have competitors who may be trying to persuade people of exactly the opposite, and don't have the power of authority to make or break careers (since one can work for competitors). But one should never take any publication as "the truth". One should read the publication for the validity of the science involved and if it is / isn't true.

https://wattsupwiththat.com/2017/11/...-to-be-broken/ 103 year record cold low for New York City set
Records were set over the past two days at Central Park, but the 144 Year old record still stands.

Dr. Ryan Maue has been tracking the forecasts for the Northeast, and the result is…ah, chilling. Maue says the “polar vortex” is responsible for the exceptionally cold and dry air invading the Northeast USA.

The previous earliest record of reaching 22°F was Nov 13, 1873. The 21°F expected for NYC would be the coldest in 144 years. Further up Long Island, temperatures are expected in the teens.

a case of higher co2 being beneficial:
https://www.frontiersin.org/articles...017.00512/full Carbon dioxide (CO2) is involved in plant growth as well as plant responses to abiotic stresses; however, it remains unclear whether CO2 is involved in the response of rice (Oryza sativa) to aluminum (Al) toxicity. In the current study, we discovered that elevated CO2 (600 μL·L−1) significantly alleviated Al-induced inhibition of root elongation that occurred in ambient CO2 (400 μL·L−1)

additional analysis of the article here: CO2 Science Setting the stage for their study, Zhu et al. (2017) note that aluminum (Al) is the most abundant metal on earth. When present in significant quantities in the soil, it can be detrimental to plant growth, disrupting physiological and molecular properties. In many instances, aluminum toxicity inhibits root elongation, even at very low concentrations, making it difficult for plants to acquire nutrients, thus leading to a reduction in both the magnitude and quality of their growth.
Searching for the potential mechanism responsible for the reduction in aluminum toxicity by elevated CO2, Zhu et al.'s additional analyses revealed that "elevated CO2 significantly reduced aluminum retention in the [root] cell wall (see figure 4c), which in turn increased aluminum resistance in rice, indicating the operation of the cell-wall-based aluminum exclusion mechanism." And, therefore, the authors conclude that "elevated CO2 can alleviate aluminum toxicity in rice," which is an important phenomenon for them to have observed.

NASA’s top climate expert, James Hansen, predicted that by 2018 the Arctic would be ice-free, and Lower Manhattan would be underwater. Democrats call him a “climate prophet.” Only six weeks left to go! https://realclimatescience.com/

when your model is found to fail to predict accurately, the theory is considered falsified.

New AGU Presentation: ‘No Increase In Earth’s Surface Temperature From Increase In CO2’ At next month’s American Geophysical Union (AGU) Fall Meeting in New Orleans (US), an independent researcher named Trevor Underwood will be presenting an equation-rich analysis that thoughtfully undermines the perspective that increases in CO2 concentrations are a fundamental variable affecting climate.

Instead, Underwood argues that the absorption band where CO2 emissivity could have an effect is likely already saturated, precluding the capacity of increased CO2 concentrations to produce atmospheric warming.

Well, it's more than six weeks to go isn't it, because he predicted an Arctic ice-free SUMMER by 2018. And did he even predict that?

But anyway, I do not regard a clipping, from some obscure provincial newspaper, as firm evidence of what someone is supposed to have said. I really doubt, for instance, the Hansen ever said, in this context, "We're toast" - but that is what this tabloid quotes him as saying. I believe he did say the quote "The Arctic is the first tipping point..." but I am unable to find where he said that, 5 to 10 years, the Arctic will be free of ice in summer. I'm not declaring that he didn't say it, I just want to see a trusted source of his actual words. Hansen has come in for considerable criticism from other climatologists. Physicist Freeman Dyson said "The person who is really responsible for this overestimate of global warming is Jim Hansen. He consistently exaggerates all the dangers... Hansen has turned his science into ideology." Eileen Claussen, president of the Pew Center on Global Climate Change, said that "I view Jim Hansen as heroic as a scientist.... But I wish he would stick to what he really knows".

You still haven't found anyone who said "the end is nigh" have you?

No, but I do believe my own eyes, and sea level hasn't risen any higher than the daily high tide takes it, the past 60+ years.

- in one place in the state of California which is about 0.1% (if that) of the Earth's surface area, so almost worthless in deciding whether or not global sea levels are rising, which itself is only one aspect of the whole phenomenon of global warming.
